There is much interest in the significance of apolipoproteins and proteins that are noncovalently associated with lipoproteins. It is possible that the high ionic strength used for isolation of lipoproteins with KBr and NaI could alter the pattern of associated exchangeable proteins. Here we describe lipoprotein classes fractionation from up to 0.5 ml of serum or plasma with buffers of physiolo...
In the field of molecular electronics, thin films of molecules adsorbed on insulating surfaces are used as the functional building blocks of electronic devices. Control of the structural and electronic properties of the thin films is required for reliably operating devices. Here, noncontact atomic force and Kelvin probe force microscopies have been used to investigate the growth and electrostat...
Snake venoms contain a rich variety of factors which affect blood coagulation. There have been few reports on the anticoagulant activity of the venom of different cobras, but no such observations have been made on the Iranian cobra, although a procoagulant factor has been described. In this study an anticoagulant factor has been purified from the venom of Naja naja oxiana using gel filtrat...
